JOINTTNG AND BAKING 1 001.

Application filed March 14, 1925. Serial No. 15,594..

To all whom it may concern:

Be it known that we, LEWIS H. JOHN and ALFRED HARRIES, citizens of theUnited States, residing at J ohnstown, in the county of Cambria andState of Pennsylvania,have invented certam new and useful Improve mentsin Jointing and Baking Tools, of which the following is a specification,reference being bad to the accompanying drawings. i r

This invention relates to improvements in jointingtools such as are usedby bricklayers and known as rakers, these tools being used for levelingor smoothing the plastic material between bricks, stones or the like, orfor cleaning out the spaces occupied by the plastic material.

One of the objects of-the present invention is to provide a verysimple,strong and convenient tool of this character having a handle anda cutter or blade detachably engaged therewith, the blade beingshiftable along thehandle so as to adjust the amount of projection ofthe blade, the blade being of such character that when it is worn downthe shank of the blade can be bent so as to form a new blade and thuseliminate the necessity of getting a new blade.

A further object is to provide a device of this character in which it isprovided with a handle having two blades at opposite ends, whichblades'may be used for different purposes, both of these blades beingadjustable and both of these blades be ing angularly bent at their endsandbeing made of material which will permit, after the cutting edge ofthe blade has worn down, of a ire-bending of the shank of the blade toform a new blade.

A stillfurther object is to provide a device of this character in whichold and worn-out blades may be thrown away and new blades secured at thehandle without difficulty.

Our invention is illustrated in the accompanying drawing, wherein Figure1 is a perspective view of a j01nting and raking tool constructed inaccordance with our invention;

Figure 2 is a top plan view of the construction shown in Figure 1;

Figure 3 is a longitudinal section of Figure 2' Figure 4: is a crosssection on the line 44i of Figure 2.

Referring to this drawing, 10 designates a handle which is preferably ofhard metal. The upper face of this handle is longitudinally grooved orrecessed, as at 11, this groove or recess extending nearly the entirewidth of the handle and being defined by upwardly extending shoulders 12extending the entire length of the handle. The ends of the handle slopedownward and outward and the face of the handle opposite from the recessll'is recessed, as at 13. This handle is provided adjacent its oppositeends with apertures 15 for the passage of bolts.

Coacting with the recessed face of the T handle are the two blades 16and 17. Each of these blades is longitudinally slotted, as at 18, andthe blade 16 is angularly bent, as at 19, and the blade 17 is angularlybent,

as at 20. These bends are right angle bends,

but it will be noted that the blade 16 has a longer pointer or cuttingportion 19 than the blade 17. Passing through the apertures.

15 are the bolts 21, the heads of the bolts lying upon the faces of theblades 16 and 17 and the bolts carrying the wing nuts 22.

With this construction it is obvious that the blades may-be shiftedlongitudinally within the recess 11 so as to project the blade to agreater or less extent and thus the distance between the blade and theadjacent end faces of the handle is adjusted. After the blade has beenadjusted, it is held firmly in position by means of the nut 22, the sidewalls 12 preventing any lateral movement of the blade. It will be seenthat with this device two cutters are used, one on either end, set sothat two depths of joints can be raked Without changing the cutters and,of course, the depth of the cutter 19 or 20 will depend upon the job tobe done.

This raker is practical, easy to handle and adaptable to various sizesof Work owing to the readiness with which the blades can be changed andother blades used. The rakers now on the market are so made that whenthe cutter or raker end has worn down, the whole instrument has to bethrown away.

It will be seen that there are very few parts to this device, it is veryeasy to handle in asmuch as it has a relatively large body, and it isnot hard on theoperators hand because this body is relatively thick. Oneof the important advantages is that When the point or cutter has worndown there will still be enough stock left upon the shank of the cutterto turn it up to form another point or blade. Furthermore,- an operatorcan readily turn up the opposite ends of a blade so as to form twopointers or cutters of ditl'erei'it sizes.

The rccessing of the handle 10, as at 13,- makes this handle relativelylight and the ends of the handle 10 are beveled so as to have as small asurface as possible in rubbing contact with the framework and to placethe point of contact of the framework away from the joint, as this givesa better leverage to work against and not mar the framework.

lVe have illustrated wing nuts 22, but it is to be understood that otherforms of nuts might be used.

o claim:

1'. A jointing tool for bricklayerscomprising a handle'having alongitudinally'extending recess upon one face, the recess being definedby upwardly extending slioulders and the handle being perforated throughto said recess, a blade angularl'y bent to provide a cutter' and ashank, the shank lying in said recess and beinglongitudinally slotted,and a bolt passing through said slot in the shank and through saidhandle and carrying a nut whereby the blade may be shiftedlongitudinally upon the handle.

2. A jointing tool for bricklayer-s comprising a handle, one facethereof being lon itudlnall recessed alon its entire length, the handlebeing provided adjacent its ends with bolt openings, blades disposed atopposite ends of the handle, each blade comprising a shank and cutterportion, the shank of each blade being longitudinally slotted, and boltspassing through the apertures in the handle and through the slots of theblades and carrying nuts.

3. A tool of the character described comprising a handle approximatelyrectangular in cross section, the handle being longitudinally recessedupon its upper face to provide two parallel shoulders extending from endto end of the handle, the under face of the handle being longitudinallyrecessed nearly its entire length and the handle being transverselyperforated adjacent its ends, blades mounted upon the ends of thehandle, each blade having a shank portion and a cutter portion, theshank portion of each blade being longitudinally slotted, and boltspassing through said slots and through the perforations in the handleand carrying nuts.

In testimony whereof we hereunto atlix our signatures.

LEWIS H. JOHN. ALFRED HARRIES.
